GRAIN SCALE AND REGISTER.

SPECIFICATION forming part of Letters Patent No. 376,044, dated January 3, 1888.

Application filed July 25, 1887. Serial No. 245,207. (No model.)

To all whom it may concern.

Be it known that I, LESTER RnYNoLDs, a citizen of the United States, residing at Yreka, in the county of Siskiyou and State of Califorma, have invented certain new and useful Improvements in Grain-l/Veighers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Fig. 6 is a horizontal section on line was, Fig.1. Fig. 7 is a sectional detail side view showing one of the scale mechanisms as set and sprung in dotted lines.

This invention relates to improvements in automatic weighing-machines; and it has for its objects to provide amachine in which the grain or other material is weighed and delivered from the scale-bin automatically, and in 0 which the movements of the scale-bin actuate suitable mechanisms for registering the number of times the bin has been filled, so that the amount of material passed through the machine can be accurately determined.

3 5 To these ends the invention consists in the novel constructionand arrangement of parts hereinafter described, illustrated in the drawings,and particularly specified in the appended claims.

0 Referring to the drawings by letter, A designates a casing in which I preferably mount my weighing and registering mechanisms.

This casing is of general rectangular shape and stands upon one end, and has its top end provided with ahopper, a, through which the material is fed into 'the machine. The top is preferably hinged, so that it can be raised to permit access to the interior of the casing.

a designates the front hinged door of the casing, hereinafter referred to.

In the interior upper portion of the casing A is mounted the scale-bin B. This bin is divided into twohoppers, bb, byacentral vertical partition,b and each hopper has a downwardly and outwardly inclined bottom, b the upper ends of which meet below partition I; and form a close joint therewith and with each other. At the lower ends of bottoms b the outer sides of the hoppers are cutaway, forming openings 7), through which the grain is 6: delivered from the hopper onto a double-inclined chute, C, which has its apex vertically below the central partition of the bin, andv which is adapted to conduct the material delivered from the bins to the opposite sides of 6 5 the same and deliver it into any proper receptacle or delivery spout or pipe.

D designates a horizontal shaft mounted in suitable bearings in the rear wall of easing A and in a front vertical partition or standard, A. Above the chutes C on this rod the bin B is mounted, at the junction of its bottoms and central partition, in suitable manner, so that the bin, which is of less width than the interior of the casing, can oscillate freely on 7 5 said shaft D.

d d designate outstanding lugs or arms secured to the opposite sides of the bin, and which are adapted to play through vertical slots a formed in the side walls of the casing A, when the bin is suitably oscillated. These lugs engage the weighing mechanisms, one of which is located on each side of the machine, and are similar in construction and operation. They are constructed as follows:

E E designate rectangular frames secured to the upper portions of the sides of easing A.

F F designate horizontal beam-arms pivoted at their rear ends to the side rails of frames E. The arms F are formed with two 0 converging arms, ff, on their upper sides, which do not, however, meet.

G G designate vertical latchheaded rods or bars composed of two similar pieces, 9 g, having an integral head, 9, rising from beams F, 5 and embracing the beams centrally between the arms ff by their pieces 9, as shown. The outer ends of the beams F are provided with the usual scale-marks and weights, and are kept from sidewise swinging by means of ver' 10o tically-slotted piecesf, as shown. The upper I naled by its shafti in suitable bearings in I ends of rods G stand opposite openings a and are guided laterally by slotted pieces aflwhich are set so that the heads of bars G will be kept in proper position for engagement of arm cl of the bin.

ff designate suitable springs adapted to hold rods G in proper position.

H H designate flat bars lying between the pieces 9 g of bars G, and extending from the head 9 thereof down to and between the arms ff of beams F. The bars II are pivoted centrally of their length to the bars G, as shown, and oscillate laterally on their pivots.

The operation of this part of the apparatus is as follows: The bin B is turned to one side, so that the arm d on that side will engage the hooked head 9' of rod G of its corresponding weighing mechanism. When in such position, the mouth of the hopper is closed by abutting against a suitable piece, B, secured to the inner sides of easing A, so that as long as the bin is inclined toward that side its mouth is closed. There are similar pieces B for each hopper b b of the bin. The weights on the scale-beams are then properly set and material is fed into the bin through hopper a. This hopper has its mouth contracted, so that the oscillations of the bin will turn its partition I) to either side of the hopper-mouth, and material entering the bin therefrom will be directed by the partition into either hopper b or b, according to the position of the bin, the hopper being filled always being the highest one, relatively, and opposite that engaged by its arm d with the weighing mechanism. Now, when the hopper is filled sufficiently to balance the weight on the scale-beam F, to which the bin is engaged,as described, the bin is oscillated on shaft D, and it begins to lift the beam F through its described connections. This lifting of beam F causes its outer arm, f, to engage the lower end of bar H and oscillate it on its pivot, forcing its upper end outward, and thereby engaging the arm d, and causing the bar G to disengage its head therefrom, and immediately upon the disengagement of arm d and head the bin is forcibly oscillated to the other side of the casing by the weight of the grain in the hopper of the bin, and the arm (1 on that side is engaged with the weighing mechanism and operated by the filling of the opposite hopper of the bin, which is then in position to receive grain from hopper a. As the bin is oscillated the mouths of its hoppers are freed from pieces B, and the material can escape freely into chute C. The weighing mechanisms are preferably protected by hinged doorsc on frames E. After the release of the bin the return of beam F to its normal position by its weight will also cause the lever H, by the opposite arm, f, of the beam, to be returned to its normal position, as is evident.

I will now describe the registering devices. To the outer side of partition A, and joursaid partition, and a similar partition, A or other support outside of partition A, is a large ratchet-wheel, I, the upper periphery of which extends slightly above the shaft D.

J is asmall gear-wheel 011 the shaft of wheel I, and rigid with the latter, so that they turn simultaneously. The teeth of wheel I are preferably one hundred in number. The gearwheel J engages with the teeth of a large gearwheel, K, suitably mounted below the same on a shaft 70, the relative sizes of the wheels J and K being such that the former makes ten revolutions to one of the latter.

L designates a pawl engaging wheel I, which pawl is mounted on a stud or pin, Z, secured to the side of bin B, and playing through asuitable slot in partition A. The pin Z is set at such a distance from shaft D that its movement, and consequent movement of pawl L, owing to the oscillations of bin B, will only actuate wheel I one notch, so that said wheel is moved one notch for every filling of both hoppers b b of bin B.

M designates a suitable brake-pad hinged above wheel I and controlled by a spring, m, as shown, serving to prevent undue rotation of Wheel I.

N designates a suitable dial-plate placed outside wheels I K on partition A and having dials n n for the respective wheels I K.

O designates an index-arm on the extended shaft 2' of wheel I, and 0 an index-arm on the shaft of wheel K. The dial N of wheel I is divided into units up to one hundred, so that fractions of a hundred filling of the bin can be ascertained, and the dial nis divided into hundreds up to a thousand, so that at a glance any number of times that the bin has been filled and emptied up to one thousand can be ascertained, and by multiplying such number by the added weights of the two weighingbeams F the total weight of material passed through the bin can be ascertained. The dials n n are protected by the door a of the casing.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with an oscillating grain-holding bin having an outstanding arm, of a scale mechanism for engaging the arm of the bin, com-posed of a horizontal scale-beam, F, having arms f f, the hook-headed bar G, pivoted to beam F, and the lever-bar H, pivoted to bar G and actuated by the arms f upon the lifting of beam F to cause the disengagement of bar G and the arm of the bin, as described.

2. The combination, with a suitable supporting-casing, of an oscillating bin, B, having hoppers b I), mounted on a transverse shaft, D, arms (Z (Z on opposite sides of said bin playing through openings in the sides of the casing, and scale mechanisms on each side of the bin adapted to automatically engage and release the bin as it oscillates, each composed of the scale-beams F, having arms f f, spring-controlled hook-bar G, and pivoted lever-bar H, all constructed and operating as described.

3, The combination of the oscillating bin 13, having vertical partition I) and inclined bottoms b mounted on a transverse shaft, and a hopper, a, adapted to deliver grain to the bin,

, with the scale mechanisms composed of beams F, rods G, and levers H and their connections,

. and the registering mechanisms composed of wheels I, J, and Kand their connections operated by the oscillations of the bin, all constructed, arranged, and operating substantially for the purpose set forth.

4. Thecombination of casing A, having hopi per a and chute G, the oscillating bin B, having hoppers b b, the pieces B, secured to the casing and closing the mouths of the hoppers b b, and the arms d d, with the scale mechanisms inclosed in frames E E on the sides of the LESTER REYNOLDS.
